Property list invalid for format: 200 (property lists cannot contain objects of type 'CFNull') Attempt to set a non-property-list object

Question

I'm getting a weird error when using Ti.App.Properties.setList() method.

Here you can see that i have some values. Console:

[INFO] :   id==2251378
[INFO] :   category==[object Object]
[INFO] :   localteam.id==18650
[INFO] :   visitorteam.id==7636
[INFO] :   j==1
[INFO] :   i==2

Now i getlist(); and save in a variable, and in second line create an object and initialize it. And assign some values in it. My Code is:

var myMatchesFootball = Ti.App.Properties.getList('myMatchesFootball');
myMatchesFootballObject = new Object();

myMatchesFootballObject.matchId = "";
myMatchesFootballObject.data    = "";
myMatchesFootballObject.local   = "";
myMatchesFootballObject.visitor = "";
myMatchesFootballObject.index_j = "";
myMatchesFootballObject.index_i = "";


myMatchesFootballObject.matchId = json2.scores.category[e.source.star_indexi].matches.match.id;
myMatchesFootballObject.data    = json2.scores.category[e.source.star_indexi];
myMatchesFootballObject.local   = json2.scores.category[e.source.star_indexi].matches.match.localteam.id;
myMatchesFootballObject.visitor = json2.scores.category[e.source.star_indexi].matches.match.visitorteam.id;
myMatchesFootballObject.index_j = e.source.star_indexj;
myMatchesFootballObject.index_i = e.source.star_indexi;
myMatchesFootballObject.selectedDay  = "myMatches";

myMatchesFootball.push(myMatchesFootballObject);
Ti.App.Properties.setList('myMatchesFootball', myMatchesFootball);

But my app crash and show this error in console,

The Error is: 
[ERROR] :  Script Error {
[ERROR] :      column = 62;
[ERROR] :      line = 888;

But when i comment this line it working fine,

myMatchesFootballObject.data    = json2.scores.category[e.source.star_indexi];

I am also try this but not working,

myMatchesFootballObject.data    = new Object;

The reason why you are having this error is because you are trying to save nested objects and the setList/getList API does not support it, therefore you get the error Attempt to insert non-property list object

The solution for that is to stringify that object and store it, but, I would not recommend that as a best practice. You should probably use a database using Alloy models instead of saving this in the Ti.App.Properties

A few things that you can change in your code to improve it:

Default the variable to an empty array.

var myMatchesFootball = Ti.App.Properties.getList('myMatchesFootball', []);

Instead of calling new Object, just declare the object and assign the values right to it. (Don't forget the var at the beginning)

var myMatchesFootballObject = {
    matchId: json2.scores.category[e.source.star_indexi].matches.match.id, 
    data: JSON.stringify(json2.scores.category[e.source.star_indexi]),
    // Add other values
};

The rest is ok:

myMatchesFootball.push(myMatchesFootballObject);
Ti.App.Properties.setList('myMatchesFootball', myMatchesFootball);

Thank you, as you mention i am already done this task to stringify my JSON object. And i don't have experience on local database that's why i am not using database. And Thanks for improving my code. let me try. — Abubakar, Jan 24 '17 at 10:58
No problem. If you find the answer as correct don't forget to mark it for others to use it. It may be a good idea for you to start with Alloy models - you can follow this link http://docs.appcelerator.com/platform/latest/#!/guide/Alloy_Models to get started. Using the Ti.App.Properties to store a lot of information will cause eventually slowness in the app. — Cesar Cavazos, Jan 24 '17 at 18:19
